M4CE(v5) - Host and Target Projects

This blueprint creates a Migrate for Compute Engine (v5) environment deployed on an host project with multiple target projects.

The blueprint is designed to implement a M4CE (v5) environment on-top of complex migration landing environments where VMs have to be migrated to multiple target projects. It also includes the IAM wiring needed to make such scenarios work.

This is the high level diagram:

Managed resources and services

This sample creates\updates several distinct groups of resources:

projects
- Deploy M4CE host project with required services on a new or existing project.
- M4CE target project prerequisites deployed on existing projects.
IAM
- Create a service account used at runtime by the M4CE connector for data replication
- Grant migration admin roles to provided user or group
- Grant migration viewer role to provided user or group

Variables

name	description	type	required	default
migration_admin	User or group who can create a new M4CE sources and perform all other migration operations, in IAM format (`group:foo@example.com`).	`string`	✓
migration_target_projects	List of target projects for m4ce workload migrations.	`list(string)`	✓
migration_viewer	User or group authorized to retrieve information about M4CE in the Google Cloud Console, in IAM format (`group:foo@example.com`).	`string`		`null`
project_create	Parameters for the creation of the new project to host the M4CE backend.	`object({…})`		`null`
project_name	Name of an existing project or of the new project assigned as M4CE host project.	`string`		`"m4ce-host-project-000"`

Outputs

name	description	sensitive
m4ce_gmanaged_service_account	Google managed service account created automatically during the migrate connector registration.. It is used by M4CE to perform activities on target projects.

  migration_viewer          = "user:viewer@example.com"
  migration_target_projects = [module.test-target-project.name]
  depends_on = [
    module.test-target-project
  ]
}
